Liquid reactive materials and method for using same in games and other applications

ABSTRACT

A method for temporarily adhering an image to a surface is shown utilizing liquid soluble substrates that have printed images of liquid insoluble ink. The liquid soluble substrate is positioned on a surface, such as a billboard, sidewalk, parking lot, telephone pole, skin, clothing, etc., and a liquid, typically water, is applied to the liquid soluble substrate and/or to the surface in such a quantity, and at such a temperature, and at such a pressure and velocity so as to be absorbed by the liquid soluble substrate in a sponge-like fashion. As the substrate dries, it takes on the shape of the surface, conforming and adhering to the surface through a mechanical interlock therewith. Various coatings may be applied to extend the longevity of the substrate. The liquid soluble substrate may be removed from the surface by applying a sufficient quantity of liquid at a sufficient temperature, pressure and velocity.

This application is a divisional patent application of application Ser.No. 10/374,753, filed on Feb. 25, 2003, titled “Liquid ReactiveMaterials And Method For Using Same In Games And Other Applications”,now allowed, which is a continuation-in-part of Application No.60/402,201, filed on Aug. 9, 2002, entitled “Method And System ForTemporarily Adhering An Image To A Surface”, which are incorporatedherein by reference in their entirety.

FIELD OF THE INVENTION

This invention relates to liquid reactive materials used as liquidsoluble substrates, and particularly to a method of temporarily adheringan image printed on a liquid soluble substrate to a surface, and moreparticularly to using liquid soluble substrates with an adhered image ingames and other applications.

BACKGROUND OF THE INVENTION

Available from many different suppliers, such as Gilbreth PackagingSystems, liquid soluble paper looks, feels, and tears like ordinarypaper. It can be written on, used in photocopy machines, and can becoated, embossed, and printed on. Liquid soluble paper can also belaminated, corrugated, perforated, and made into envelopes, pads, orcomputer paper. Labels made from liquid soluble paper remove instantlywith liquid without scratching or scraping, and without soggy paper oradhesive residue left behind on the surface that the label was applied.Liquid soluble paper can be printed on most web and sheet fed presses,including letterpress, flexography, and dry offset processes. Liquidsoluble paper requires no special equipment and accepts water andoil-based inks. Liquid soluble paper can be coated, impregnated,sheeted, or pleated. It can also be slit, perforated, or folded—allusing standard converting equipment.

Most liquid soluble paper completely disperses in hot or cold liquid,with water being the most often used liquid. Typically made of cellulosepolymers and tackified resins, liquid soluble paper products are simplywashed away when no longer needed. They are quickly and easily removed,from even the most inaccessible places, by utilizing a liquid sprayer,squirter, hose or other suitable device.

Although liquid soluble materials are temporary and disposable, they canbe made to last for extended periods of time and are strong enough towithstand the most rigorous production processes. They can be easilyfabricated into different shapes and sizes and are capable of beingprinted with the most demanding graphics. Many liquid soluble substratesare biodegradable and contain no preservatives, bactericides, or otherharmful substances. Many are also non-toxic, tasteless, and odorless,making them safe for almost any application.

DETAILED DESCRIPTION

Referring now to the Figures, in which like reference numerals refer tolike components thereof, FIGS. 1A, 1B, and 1C show an enlargement of aportion of a liquid soluble substrate having images printed with liquidinsoluble ink being applied temporarily to a surface in an embodiment ofthe present invention. Referring now to FIG. 1A, Liquid SolubleSubstrate 102 is positioned on Surface 100 as part of the applicationprocess. Liquid Soluble Substrate 102, which is well known in the art,is typically paper, but may also be made of other substances, such asplastic.

Printed on Liquid Soluble Substrate 102 are Ink Images 104. Both LiquidSoluble Substrate 102 and Ink Images 104 are shown with exaggerateddepth for clarity of description. The ink used to form Ink Images 104 istypically a water insoluble ink, and may be applied to Liquid SolubleSubstrate 102 in any of the ways previously described. The waterinsoluble ink may be solvent based, UV (ultraviolet) curable, orwater-based with catalyst additives to prevent dissolvability in water.Depending upon the porosity of the substrate material and the propertiesof the ink used, some of the ink may be absorbed into the substratematerial as part of or during the printing process.

In FIG. 1B, Liquid 106 (represented by the arrows), such as water, isapplied to Liquid Soluble Substrate 102 and Surface 100 in such aquantity, and at such a temperature, and at such a pressure so as to beabsorbed by Liquid Soluble Substrate 102 in a sponge-like fashion. Thecombination of quantity, temperature, and pressure and velocity ofLiquid 106 may be quite varied from one situation to another in order tocause Liquid Soluble Substrate 102 to adhere to Surface 100, which isthe desired end of the invention. Any one of these factors, or acombination of two or more of these factors, may, in any givensituation, cause Liquid Soluble Substrate 102 to dissolve and break up,rather than just absorb, and therefore not adhere to Surface 100. Forexample, if the liquid is applied with too much pressure and velocity,Liquid Soluble Substrate 102 will begin to start to dissolve and breakup. A large quantity of liquid, even if applied with low pressure andvelocity, may cause Liquid Soluble Substrate 102 to dissolve and breakup. All of these factors need to be evaluated for any given situation inorder to avoid dissolving and breaking up Liquid Soluble Substrate 102during the application process. When the combination of these factorsare appropriate for a given situation, Liquid Soluble Substrate 102absorbs Liquid 106 like a sponge and does not break up.

After Liquid 106 has been applied and absorbed by Liquid SolubleSubstrate 102, Liquid 106 is allowed to evaporate (indicated by thereverse direction of the arrows) from Liquid Soluble Substrate 102 asshown in FIG. 1C. As Liquid 106 evaporates, Liquid Soluble Substrate 102begins to conform and adhere to Surface 100. When Liquid SolubleSubstrate 102 absorbs liquid, the fibers of the substrate expand andlift from the surface. This expansion of the fibers allows it to stretchand thereby become temporarily flexible, allowing it to take on theshape of the surface so that as it dries and shrinks, the substrateconforms and adheres to the surface through a mechanical interlocktherewith. Once completely dried, based upon the local conditions oftemperature, barometric pressure, and humidity, Liquid Soluble Substrate102 with Ink Images 104 is adhered to Surface 100 due to cohesive forcesbetween Liquid Soluble Substrate 102 and Surface 100.

For different applications, variations in the substrate used can augmentthe success of the application. Some applications may need a substratewith a faster drying time. Others may require greater durability to holdup to light rain or high humidity which may be accomplished through asubstrate with a different chemical composition or an applied surfacetreatment. Thicker or thinner gauges of paper may be required to betterconform to the particular surface.

Liquid Soluble Substrate 102 will remain adhered to Surface 100 untilsuch time as a sufficient quantity of liquid at a sufficient temperatureand sufficient pressure and velocity for the given conditions will causeLiquid Soluble Substrate 102 to break up and dissolve, and Ink Images104 will wash away with the liquid, restoring Surface 100 to itscondition prior to the application of Liquid Soluble Substrate 102. Forexample, a light rainfall may not have a deteriorating effect upon anoutdoor application, whereas a heavy rainfall, or wind-driven rain ofsufficient volume may be enough to dissolve Liquid Soluble Substrate102.

When Surface 100 is subject to wear and tear, general friction will alsocause Liquid Soluble Substrate 102 to break down and either fade orbegin to tear away (i.e., the tensile strength of Liquid SolubleSubstrate 102 is such that it breaks off or rips from friction). Varioustypes of material used for Liquid Soluble Substrate 102, such as paperor plastic, will have different tensile strengths, and based upon thetraffic or wear and tear expected, a suitable material may be chosen forLiquid Soluble Substrate 102 such that the image will remain for thedesired period of time.

In the example shown in FIGS. 1A, 1B, and 1C, the printed image onLiquid Soluble Substrate 102 is that of fine text or half-tone printing.The liquid applied to the top surface of Liquid Soluble Substrate 102 isabsorbed underneath Ink Images 104 due to the spaces between the dots ofink characteristic of half-tone printing, and the spaces surrounding thefine text printing (not shown) comprising Ink Images 104. With certaintypes of printed images, such as large text, or solid full-tone images,the liquid insoluble ink used to form Ink Images 104 acts as a barrierto absorption by the applied liquid. For such situations, Liquid 106 isapplied to Surface 100 prior to positioning Liquid Soluble Substrate 102on Surface 100 such that Liquid 106 is absorbed from the bottom side ofLiquid Soluble Substrate 102. If necessary, more Liquid 106 may beapplied to the top surface of Liquid Soluble Substrate 102 afterpositioning to enhance the application process so long as Liquid SolubleSubstrate 102 does not start to dissolve.

FIGS. 2A and 2B show a liquid soluble substrate having images printedwith liquid insoluble ink conforming to the shape of the surface it isapplied in an embodiment of the present invention. Referring now to FIG.2A, Telephone Pole 200 is cylindrical in shape. Handbill 202 is a liquidsoluble paper having text printed on it with a liquid insoluble ink. Aperson (not shown) places Handbill 202 on Telephone Pole 200. The personmay use tacks, nails, staples, etc. to affix temporarily Handbill 202 inthe desired location and orientation on Telephone Pole 200. Handbill 202may also have a thin layer of adhesive on the non-printed side whichwill allow Handbill 202 to be affixed temporarily to Telephone Pole 200.The adhesive layer is very useful for vertical applications orapplications on a ceiling or surface where gravity, or even wind, wouldtend to keep the liquid soluble substrate from staying in place duringthe application process. The person may also just hold Handbill 202 inthe desired location and orientation during the application process.

Different types of adhesives may also be employed based upon theapplication, such as a quicker drying adhesive, or an adhesive that morequickly dissolves when applied to a wet surface, and then dries quicklythereafter. Water-based emulsion adhesives are suitable for thispurpose. A backing or release liner may be used to mask the adhesive sothat the material does not stick to itself (e.g., when the substrate isin rolls or stacked in sheets one on top of the other). The releaseliner can be made of any suitable material that prevents the adhesivefrom bonding prematurely.

The person, or another person, then applies a liquid to the surface ofHandbill 202 as describe above so as to not cause the liquid solublesubstrate to dissolve, but applies enough liquid to allow sufficientabsorption of the liquid. As discussed above, liquid may also be appliedto the surface of Telephone Pole 200 prior to positioning Handbill 202.The liquid is allowed to evaporate while Handbill 202 is secured inplace on Telephone Pole 200 by the person, or by the nails, tacks, oradhesive, etc.

Examples of other applications include applying the liquid solublesubstrate having images printed with liquid insoluble ink on a sidewalkor tennis court for advertising purposes. Another application can be foruse on a playground or parking lot for use as a temporary court or game.For example, rather than being a solid sheet or series of panels as usedin billboard advertising, the liquid soluble substrate with liquidinsoluble ink images could be in the form of a tape on a roll that isused to temporarily mark out the boundaries of a tennis court orbasketball court. The markings can later be washed away so that theplayground or parking lot is restored to its original condition for itsoriginal use.

FIG. 2B shows that after the liquid has evaporated, Handbill 202 isadhered to Telephone Pole 200 and has conformed to the shape ofTelephone Pole 200.

FIGS. 3A and 3B show an enlarged section of a portion of the liquidsoluble substrate having images printed with liquid insoluble ink and aportion of the surface it is applied as shown in FIGS. 2A and 2B in anembodiment of the present invention. Referring now to FIG. 3A, SurfaceSection 300 represents a small surface portion of Telephone Pole 200(FIGS. 2A and 2B), which indicates the rough, uneven Texture 306 of atypical telephone pole. Handbill Section 302 represents a small portionof the lower left hand corner of Handbill 202 (FIGS. 2A and 2B) havingthe letter “A” as an Ink Image 304. Handbill Section 302 is shown priorto being applied to Surface Section 300, and prior to wetting with aliquid.

FIG. 3B shows Handbill Section 302 after it has been applied to SurfaceSection 300, and after liquid has been applied and after the liquid hasevaporated, as Handbill Section 306. Not only has Handbill Section 306conformed to the shape of Telephone Pole 200 as shown in FIG. 2B, but ithas also conformed to Texture 306 of Surface Section 300. Ink Image 304has also conformed to Texture 306 of Surface Section 300 and is shown asInk Image 310 in FIG. 3B.

The method and system for temporarily adhering an image to a surface ofthe present invention has numerous applications. For example, the methodand system of the present invention could be applied in advertising tothe hundreds of thousand of billboards in service in this country, aswell as around the world. For extended outdoor uses, a light layer of acoating, varnish, or other surface treatment may be applied towaterproof the surface so that normal rainfall will not cause the liquidsoluble substrate to dissolve, yet allow the billboard to be “erased”for a new ad by a pressurized liquid sprayer, squirter, hose, or throughapplication of a substance that will first dissolve the surfacetreatment, thus allowing the liquid, or some other liquid such as water,to then dissolve the liquid soluble substrate. The coating or varnishmay also be UV (ultra-violet) biodegradable such that over time, e.g.,30 days, the coating degrades, thereby allowing the substrate todissolve with conventional application of water, or even rain of asufficient velocity and volume.

Besides billboards, the method and system of the present invention maybe applied to sidewalks, the sides and roofs of buildings, basketballcourts, tennis courts, poles, trees, fences, windows, ceilings,automobiles, trucks, train cars, airplanes, and literally any otheraccessible surface. Special UV (ultra-violet) inks may be used foroutdoor applications. Sunlight causes the UV ink to harden or cure,becoming plastic-like, and thus increasing the integrity of the imageand lengthening its brilliance and durability.

FIG. 4 shows a block flow diagram of an embodiment of the method oftemporarily adhering an image to a surface of the present invention.Referring now to FIG. 4, a surface is selected in step 402 fortemporarily adhering an image, such as a sidewalk, billboard, parkinglot, pole, etc. In step 404 a determination is made, based upon thenature of the liquid insoluble image on the liquid soluble substrate, ifthe surface needs to be wetted prior to positioning the liquid solublesubstrate on the surface. If yes, then in step 406 the surface ispre-wetted with the liquid. If not, then control flows to step 408.

In step 408, with or without pre-wetting, the liquid soluble substrateis positioned on the surface at the desired location and orientation. Aliquid soluble substrate with an adhesive backing may be used forvertical or semi-vertical surfaces, whereas a horizontal orsemi-horizontal surface would not require an adhesive backing, but couldbe used if desired. The liquid soluble substrate could also be tacked,nailed, stapled, etc. A determination is made in step 410 if anadditional wetting, or the initial wetting is required. If yes (eitheran additional wetting or the initial wetting) then in step 412 liquid isapplied to the liquid soluble substrate. If not, then control flows tostep 414.

In step 414 the liquid used to wet the liquid soluble substrate and/orthe surface is allowed to evaporate. As the liquid evaporates, thefibers of the liquid soluble substrate, which stretched and expanded andlifted from the surface during absorption, takes on the shape andtexture of the surface as it dries and shrinks so that the substrateconforms and adheres to the surface through a mechanical interlocktherewith. Once completely dried, based upon the local conditions oftemperature, barometric pressure, and humidity, the liquid solublesubstrate with the liquid insoluble image adheres to the surface due tocohesive forces between the two.

Step 416 determines, based upon the application, if a surface treatmentneeds to be applied to the liquid soluble substrate with the liquidinsoluble image. Such a surface treatment may include, but is notlimited to, a coating or varnish that may help to waterproof the liquidinsoluble image or protect it from fading. If yes, then in step 418 thesurface treatment is applied. If not, then control flows to step 420. Insome applications, the surface treatment may be applied at the beginningof or during evaporating step 414.

In step 420, with or without surface treatment, the liquid insolubleimage on the liquid soluble substrate is allowed to remain on theapplied surface for a predetermined period of time. The time period willvary from application to application. For example, for billboard space,the advertising image placed on the billboard may be placed for a week,several weeks, or months at a time. Advertising may be placed on atennis court surface during the course of a tournament, or for just onematch. Once the time period has expired, then in step 422 the liquidsoluble substrate with the liquid insoluble image is removed. A liquidis applied, typically water, at a sufficient quantity at a sufficienttemperature and sufficient pressure and velocity for the givenconditions to cause the liquid soluble substrate to dissolve, washingaway the liquid insoluble image, and thus restoring the surface to itscondition prior to the application of the liquid soluble substrate. If acoating or varnish has been applied, a substance designed to break downthe coating or varnish may be applied first, followed by a removingliquid, such as water. The method of the present invention thus ends.The surface is now ready to receive a new image, and the method of thepresent invention may be repeated.

FIG. 5 shows an embodiment of the method of temporarily adhering animage to a surface of the present invention where the surface is thehuman body or clothing for the purpose of playing a game. Referring nowto FIG. 5, in this embodiment of the invention, a liquid solublesubstrate, in the shape of targets, has images printed with liquidinsoluble ink. The targets are then adhered temporarily to the humanbody, skin or clothing, for the purpose of playing a game. The targetsmay be of any suitable shape, such as round, square, rectangular,triangular, elliptical, diamond, star-shaped, heart-shaped, and thelike. The images printed may be of any type of design or text or bothand with single or multiple colors, but preferably with a singledominant color.

In one game that utilizes the present invention called Splash Tag™,typically two teams are formed, Team One and Team Two, where each teamhas one or more individuals who make up each team. More than two teamsmay be formed, in which case each team is pitted against each of theother teams. In preparation for play, members of Team One apply aplurality of targets to their bodies, preferably of a first dominantcolor and/or design. Members of Team Two also apply a plurality oftargets to their bodies, preferably of a second dominant color and/ordesign in order to more readily distinguish the members of Team One fromthe members of Team Two. If additional teams are formed, additionaldominant colors and/or designs are typically used to distinguish eachmember of a team from all other members of all other teams. Team Member500 of FIG. 5 is exemplary of team members from either Team One or TeamTwo or any additional teams. A plurality of different size targets, byway of example, but not limited to, Large Targets 502, Medium Targets504, and Small Targets 506 may be temporarily adhered to Team Member 500through wetting as described above in reference to the description ofFIGS. 1-4. In an alternative embodiment, Large Targets 502, MediumTargets 504, and Small Targets 506 have an adhesive back side whichallows them to be adhered to Team Member 500 without wetting. Theadhesive back side may be protected with a backing that must be removedbefore the target can be adhered to the body. Such backings are wellknown in the art, such as a crack-and-peel type backing. Once theprotective backing is removed, the target is positioned on the desiredlocation of the body and then pressed onto the body, causing the targetto conform and adhere to the body. With either method of adhering, thetargets may be applied directly to skin or to whatever clothing TeamMember 500 is wearing, such as the shirt and swim trunks shown in FIG.5.

By way of example, Large Targets 502 may be applied to the stomach area,shown applied as Large Target 502′, and applied to the back area (notvisible) of Team Member 500. Medium Targets 504 may be applied to theleft and right shoulder areas, shown applied as Medium Targets 504′, andmay be applied to the left and right thigh areas, shown applied asMedium Targets 504″ of Team Member 500. Small Targets 506 may be appliedto the forehead area, shown applied as Small Targets 506′, and may beapplied to the back of the neck (not visible) of Team Member 500.

Splash Tag™ is played in a manner similar to laser tag, paint ball, orcapture the flag, or in a fashion that combines elements from two ormore of these games. Each team member of Team One, Team Two, and anyadditional teams is equipped with one or more liquid shooting/squirtingdevices, such as squirt guns, squirt bottles, large capacity “supersoaker” or “blaster” type squirt guns, and the like. Water is a typical,safe, and easily obtainable liquid that may be used with theshooting/squirting devices. However, any other suitable liquidcompatible with the shooting/squirting devices that will react with thetargets could be used.

The object of the game is for each team member to pursue and shootliquid at the targets adhered to the body of an opposing team member,the liquid causing the targets to dissolve when hit. Once a team memberhas had all of his or her targets dissolved from his or her body, theteam member is out of the game and cannot shoot at anyone else. A teamwins when all of the team members from all of the other teams have beeneliminated from the game. Team members are free to move about within thepredetermined area of play in order to pursue opposing team members soas to shoot their targets, or to evade opposing team members to avoidthe loss of one's own targets.

Additionally, one or more of Large Targets 502, Medium Targets 504, andSmall Targets 506 corresponding to the dominant color/design designationof Team One and Team Two and any additional teams may be adhered tosurfaces of objects within the predetermined area of play. For example,each team may have an area designated as their home base with targetsplaced on the surface of the home base. In addition to eliminating thetargets from the bodies of team members, the targets placed on thesurface of objects of the home base must also be eliminated. The targetsmay be adhered to a variety of surfaces serving as the home base,including by way of example, but not limited to, glass, concrete, brick,asphalt, plastic, vinyl, metal, wood, chain link fence, rock, and thelike.

By varying the level of ink coverage and pattern of ink application, thesolubility of the substrate material can be varied, both in the time ittakes to dissolve, and also the amount of water required to make thetarget dissolve. Various surface coatings may also be applied to affectthe solubility of the targets. Thus, the number of hits and amount ofwater applied to completely dissolve a target can be adjusted to make itharder or easier to dissolve a target. The targets may also be treatedso that they glow in the dark for night-time play. Many other variationsof game play and game rules may be added, such as the ability of a teammember to earn back one or more of his or her targets that have beendissolved. For example, a team member may earn back a target byeliminating an opposing team member, or for eliminating one or more homebase targets from an opposing team's home base.

In another embodiment of the invention, the targets may not react bydissolving when hit with the liquid, but instead react by changingcolor. Targets constructed with materials having thermo-chromatic orhydro-chromatic properties will change color when hit by the liquid. Athermo-chromatic material, when adhered to the body of a team member,will be at a temperature substantially the same as the skin temperatureof the team member. The liquid, typically being several tens of degreescooler than skin temperature, will cause the thermo-chromatic materialto change color upon coming into contact with the thermo-chromaticmaterial of the target. The temperature differential between the targetand the liquid need only be the minimum differential at which thethermo-chromatic effect will take place. A team member is eliminatedwhen all of the targets on the team member have changed color.Similarly, a hydro-chromatic material will change color simply whencontacted by a liquid.

Many other types of games may also be played utilizing the targets ofthe present invention by dissolving the targets with liquid. Aspects ofthe various games may revolve around one or more of accuracy, speed,distance, accumulating points, eliminating opposing players, and thelike. The other games may involve teams, one on one, or singleindividuals playing alone.

Having described the present invention, it will be understood by thoseskilled in the art that many and widely differing embodiments andapplications of the invention will suggest themselves without departingfrom the scope of the present invention.
